To all whom t may concern:

Be it known that l, ABRAHAM KARASTI, a citizen of Finland, residing at Clatskanie, in the county of Columbia and State of Oregon, have invented certain new and useful Improvements in Grapples, of which the following is a specification.

This invention relates to hoisting, and particularly to the class of grapples; its object is to provide a grapple adapted to draw' up stumps and obstructions generally from river bottoms, lakes and other bodies of water. The construction kand operation of the device is such that the presence of a strong current in the body of water will not impede its work.

With the foregoing and other objects in View the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed outin the claims and illustrated in the accompanying drawings which form a part of said. specification and in which- Figure 1 is a front view of my grapple in open position. Fig. 2 is a side view of the' same. Fig. 3 is a front view in closed position. Fig. 1 is a side view of the same as carried by a small boat showing the manner of locating an obstruction. Fig. 5 is an enlarged view of a portion of the grapple frame and one of the arms carried thereby, Fig. 6 is a perspective view of one of the aws. J Like reference characters'indicate corresponding parts throughout the several views. The reference character 1 designates a boat which may be provided with brackets 2 that carry the posts 3. Where the depth of the water is known a cable 4 may have its ends secured to the posts 3 and said cable serve as a drag to comb the water bed in search of stumps or other obstructions 5. When a stump is engaged bythe drag the boat is brought to a standstill and anchored and the grapple lowered upon the drag to engage the obstruction. The grapple com# prises a frame 6, preferably of square or oblong shape, the sides of which carry the brackets 7 to which the sectional pulley arms 8, swiveled together at 9, are hinged; said swiveled arms carry the pulleys 10 that ride over the drag 4 and support the frame 6. The frame 6 is further provided with oppositely disposed castings 11 at one end and to said castings the angular arms 12 are pivotally connected, Aeach of said arms being terminally provided with a jaw 13 the teeth of which are adapted to bite into an obstruction 5. The arms 12 are manipulated by means of a control rope 14, manually operated or secured to a windlass, which is secured to a ring 15 which is connected by pitmen 16, 16 with said arms and, further, by means of another control rope 17, operated by a second windlass or by hand, that passes through the ring 15 and through apertures 18 in the frame 6 and engages another ring 19 from which pitmen 20, 20 eX- tend to said arms 12 near their lower termination.

Vhen an obstruction is located by the drag the frame 6 is lowered over the same, a pull upon the rope 14 keeping the arms 12 and jaws 13 in open position. When the frame Vreaches the vicinity of the obstruction pressure upon the rope 14: is removed and a pull exerted upon the rope 17 to bring vthe arms and jaws together upon the oblar arms, eXible means connected to said pitmen for opening said jaws, pitmen connected to the lower portions of said arms and flexible means connected to said last named pitmen for closing said jaws.

2. A grapple comprisingadrag, awheeled frame operative over said drag, jaw-bearing arms pivotally connected to said frame, pitmen connected to the upper portions of said jaw-bearing arms, fleXiblemeans connected to said pitmen for opening said jaws; pitv ture in the presence of two subscribing Witmen connected to the lower portions of said nesses.

jaw-bearing arms and flexible means conneoted to said last named pitmen for clos- ABRAHAM KARASTI' ing said jaws. Witnesses In testimony that I claim the foregoing Y ABE KARVONEN, as my own I have hereto aniXecl my signa- HERMAN LUOKKANU.
